Translated View the article in English 如何使用 Kerberos 认证使 UrlToPdf 工作? 要使用 Kerberos 认证与 IronPDF 的 UrlToPdf,您应该在渲染设置中设置用户名和密码。 您可以参考 IronPDF 文档获取更多详情:IronPdf.ChromeHttpLoginCredentials。 我们推荐使用 System.Net.Http.HttpClient 下载 HTML 内容,随后您可以进行渲染。 这种方法允许您在 IronPDF 处理内容之前处理包括需要认证的 HTTP 请求。 这里有一个关于使用 Kerberos 下载页面的在线指南:System.Net.Http.HttpClient 如何选择认证类型?。 这个 StackOverflow 链接提供了有关使用 HttpClient 实现认证的详细讨论。 为了解析并确保下载 HTML 中的所有必要资源,考虑使用 HTML Agility Pack。 这个 .NET 库有助于有效地操作和查询 HTML 文档。 // Example: Using HttpClient with Kerberos Authentication // Import the necessary namespaces using System; using System.Net; using System.Net.Http; using System.Net.Http.Headers; using System.Threading.Tasks; namespace KerberosAuthenticationExample { class Program { static async Task Main(string[] args) { // Create an instance of HttpClient HttpClientHandler handler = new HttpClientHandler { // Automatically use default network credentials UseDefaultCredentials = true // Enables Windows authentication (e.g., Kerberos) }; using HttpClient httpClient = new HttpClient(handler); try { // Send a GET request to the desired URL HttpResponseMessage response = await httpClient.GetAsync("https://your-secure-url.com"); // Ensure the request was successful response.EnsureSuccessStatusCode(); // Read and display the response body string responseBody = await response.Content.ReadAsStringAsync(); Console.WriteLine(responseBody); // If needed, render the HTML to PDF with IronPDF here // IronPdf.HtmlToPdf renderer = new IronPdf.HtmlToPdf(); // renderer.RenderHtmlAsPdf(responseBody).SaveAs("output.pdf"); } catch (HttpRequestException e) { // Handle any error responses from the server or connection issues Console.WriteLine("\nException Caught!"); Console.WriteLine($"Message :{e.Message}"); } } } } // Example: Using HttpClient with Kerberos Authentication // Import the necessary namespaces using System; using System.Net; using System.Net.Http; using System.Net.Http.Headers; using System.Threading.Tasks; namespace KerberosAuthenticationExample { class Program { static async Task Main(string[] args) { // Create an instance of HttpClient HttpClientHandler handler = new HttpClientHandler { // Automatically use default network credentials UseDefaultCredentials = true // Enables Windows authentication (e.g., Kerberos) }; using HttpClient httpClient = new HttpClient(handler); try { // Send a GET request to the desired URL HttpResponseMessage response = await httpClient.GetAsync("https://your-secure-url.com"); // Ensure the request was successful response.EnsureSuccessStatusCode(); // Read and display the response body string responseBody = await response.Content.ReadAsStringAsync(); Console.WriteLine(responseBody); // If needed, render the HTML to PDF with IronPDF here // IronPdf.HtmlToPdf renderer = new IronPdf.HtmlToPdf(); // renderer.RenderHtmlAsPdf(responseBody).SaveAs("output.pdf"); } catch (HttpRequestException e) { // Handle any error responses from the server or connection issues Console.WriteLine("\nException Caught!"); Console.WriteLine($"Message :{e.Message}"); } } } } ' Example: Using HttpClient with Kerberos Authentication ' Import the necessary namespaces Imports Microsoft.VisualBasic Imports System Imports System.Net Imports System.Net.Http Imports System.Net.Http.Headers Imports System.Threading.Tasks Namespace KerberosAuthenticationExample Friend Class Program Shared Async Function Main(ByVal args() As String) As Task ' Create an instance of HttpClient Dim handler As New HttpClientHandler With {.UseDefaultCredentials = True} Using httpClient As New HttpClient(handler) Try ' Send a GET request to the desired URL Dim response As HttpResponseMessage = Await httpClient.GetAsync("https://your-secure-url.com") ' Ensure the request was successful response.EnsureSuccessStatusCode() ' Read and display the response body Dim responseBody As String = Await response.Content.ReadAsStringAsync() Console.WriteLine(responseBody) ' If needed, render the HTML to PDF with IronPDF here ' IronPdf.HtmlToPdf renderer = new IronPdf.HtmlToPdf(); ' renderer.RenderHtmlAsPdf(responseBody).SaveAs("output.pdf"); Catch e As HttpRequestException ' Handle any error responses from the server or connection issues Console.WriteLine(vbLf & "Exception Caught!") Console.WriteLine($"Message :{e.Message}") End Try End Using End Function End Class End Namespace $vbLabelText $csharpLabel 关键点: HttpClient 和 HttpClientHandler:使用带有 UseDefaultCredentials = true 的 HttpClientHandler 允许使用当前用户的凭证进行 Kerberos 认证。 错误处理:实现 try-catch 块以管理 HTTP 请求期间的异常。 HTML 渲染:一旦 HTML 被获取,必要时利用 IronPDF 将内容渲染成 PDF。 Curtis Chau 立即与工程团队聊天 技术作家 Curtis Chau 拥有卡尔顿大学的计算机科学学士学位,专注于前端开发,精通 Node.js、TypeScript、JavaScript 和 React。他热衷于打造直观且美观的用户界面,喜欢使用现代框架并创建结构良好、视觉吸引力强的手册。除了开发之外,Curtis 对物联网 (IoT) 有浓厚的兴趣,探索将硬件和软件集成的新方法。在空闲时间,他喜欢玩游戏和构建 Discord 机器人,将他对技术的热爱与创造力相结合。 准备开始了吗?
